Bitcoin daemon not starting: fails to initialize the database

[darkv0rt3x]

Hello.

My situation is the following:

I have this external USB HDD with 1Tb which I was using, among other stuff, to store my blockchain folder and what I did was to create a symlink in my home dir, named .bitcoin, pointing to this data folder in this external USB HDD. However, whenever an error occurs in the database, this HDD is very slow when I ask bitcoin daemon to -reindex-chainstate.

So, I was suggested to keep only the blocks in this external HDD and move the rest of the data folder into my SDD and this way, whenever another error would occur with the blockchain folder, it would be faster to -reindex-chainstate.

What I did was to copy to my home folder, the data base folder, except the debug files and the blocks folder, and I commented out from the bitcoin core config file the follwoing lines:

Code:

#conf=/media/WdElements/blockchain-backup/bitcoin.conf
#datadir=/media/WdElements/blockchain-backup

because now, the data folder was in it's default location (at my home folder) and I started bitcoin daemon using bitoicnd -blocksdir=WdElements/blockchain-backup/ but the daemon stops shortly after saying it couldn't initialize the database.

So, what am I doing wrong?

Maybe you forgot to write, but I want to be sure: inside your current datadir, since the blocks are not there, do you have a blocks symlink to the actual blocks folder?


I see it's there now. I would try that instead of -blocksdir use a blocks symlink to the actual blocks folder.
I've done something similar in the past (i.e. managed the datadir parts with symlinks) and it worked.

I can try that, but I actually wanted to know/understand why -blocksdir is not working.

This is what I use, without any changes to my config file. I used to have a different setup with wallet symlinks, but at some upgrade that stopped working because Bitcoin Core decided to no longer accept my symlink choices. My current setup has worked ever since.

I actually wanted to know/understand why -blocksdir is not working.

I'm just guessing here: maybe because it's on a different disk.

Ok guys. I ended up creating a symlink too.

I guess I'll leave it like that fr now!
